buildingmaterials

Modern
buildings often have a wide choice of materials for a given job. For
example, a roof can be made of various metals, ceramic tiles,
concrete, or organic materials including wood and straw. The choice
of material will normally depend upon the job it is expected to do
such the load it has to bear, its price and availability, and the
look or feel it gives to the building.

The
final selection of materials will normally rest upon the advice of
professional builders and designers and the wishes of the people who
are going to live in the building. The sustainability index
cannot substitute for the advice of a professional builder or
designer, but it can encourage them to include environmental
considerations in the advice that they give.
